HARQ SEQUENCES IN WIRELESS NETWORKS

Abstract:

This disclosure provides systems, methods and apparatuses for data retransmissions in a wireless network. In some implementations, a wireless communication device may transmit a first data unit to a receiving device, may receive a first hybrid automatic repeat request (HARQ) feedback frame indicating that a portion of the first data unit was not successfully decoded by the receiving device, may retransmit the indicated portion of the first data unit to the receiving device in response to the first HARQ feedback frame, and may transmit a second data unit, different than the first data unit, to the receiving device concurrently with the retransmission of the indicated portion of the first data unit.
